Absolutely nothing.
What has changed in the last 24 hours? What good does this news do? Other than make recruits second guess signing with OU tomorrow.
Sorry man, but "we should have let recruits sign with OU based on false pretenses" isn't a PR strategy. It's clear something's going to come out about Smith that ain't good, and that he's coached his last game for us.
Once the University knows that, you have to take action ahead of signing day, right? Isn't it dishonest not to?
You're prioritizing signing day success over being honest with the kids signing about who they'd be signing with.
